To all whom, it Nba/y concern.-

Be it known that we, J osErH V. CLARK and HERBERT S. BLYNT, citizens of the United States, residing' at Steubenville, in the county of J eti'erson and State oi' Ohio, have invented certain new and useful Improvements in Lubricators; and we do declare the following to be a r'ull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures ot reference marked thereon, which form a part of this specilication.

Our invention relates to a new and useful improvement in an oil lubricating device designed and constructed with a View of automatically feeding the lubricant to any desired portion of the engine, utilizing the condensation oi' steam to Jforce the oil contained in the reservoir into the steam-line supplying the steam chest and cylinder on the engine.

ln the accompanying drawings` forming a part of this specilication, we have illustrated our invention by several views, in which- Figure 1, Sheet 1, is a vertical front view of our lubricator. Eig. 2, Sheet 1, is a vertical side view of the same. Fig. 3, Sheet 2, is a sectional view or' our invention, showing the passages formed in the head portion with a regulating-valve seated in said head portion. Fig. 4, Sheet 2, is a side sectional view of the valve and registering device employed in regulating the iiow of oil from the reservoir. Fig. is a side view of the regulating-valve and stem. Fig. 6 is an end view of the same, showing ports located therein. Fig. 7 is a side and part sectional View of the head portion of the lubricator, showing inlet-orifice to the oilreservoir. Fig. 8, Sheet 3, is a sectional View of the top of the oil-reservoir and neck of the head portion, showing sectional view of an automatic steam actuated valve attached thereto. Eig. 9 is a sectional view of the automatic valve, showing the valve-stem seated by means of hand-operated screw-stern. Fig. lO is a cross-sectional view of the automatic valve, taken on the line lO of Fig. 8.

Numerals of reference designate like parts throughout the several views, in which-- The numeral 1 represents the oil-reservoir, and 2 a removable head portion afhxed to the top of said reservoir. Seated in said head portion is a regulating-valve 3, having a straightway channel 4 and a curved channel 5 formed therein. Leading upward through the neck portion 6 of the head is a passage-way 7, its upper end communicating' with the valve 3 and its lower portion opening into the oil-reservoir. 8 is a port in said neck portion through which oil is supplied to the reservoir. Communicating with the valve-seat are the curved passages 9 and 10, the outer end of the passage-way 9 being connected with a jet 11 and the outer end of the passage-way 10 entering a condensing-head 12.

Seated between the. condensing-head 12 and jet-supporting portion is a sight-feed glass 14, surrounding said jet and being held in. position by packing-nuts 15 and 15. This sightfeed glass is so arranged that it may be easily removed in case of breakage. Only a suiicient portion of the sight-feed tube is exposed to permit of seeing the amount or' oil being fed to the engine, While the surrounding metal vwill protect the glass from breakage.

Leading at right angles with the valve-seat is a straightway passage 16, having an outside threaded portion 16 formed thereon, the latter being connected with the steam-line leading to the engine. Entering this passage 16 from the outside is aV tube-17, having' a bell-shaped end 17', the use of which will be hereinafter described. Formed at right angles and communicating with said passage 16 is a chamber 18, through which passes a tube 19, the lower end of the same being connected With a curved passage-way 20 and the upper end engaging' a nipple 13, which is connected with a pipe leading to the steam-line. This passage-Way 2O continues on down through the neck portion 2 and has located -therein a valve-stem 21. Connected with the lower end of said passage-way 2O is a tube 22, which enters the oilreservoir, extending down through the same nearly to the bottom portion thereof. inserted through a plug in the bottom of the reservoir is a drain-valve 23.

The regulating-valve 3 is held in position by a spring 24, seated around the valve-stem TOO 3, the ends of said spring engaging the valve and box 25. Seated around the valve-stem 3' is a packing-ring 26, held in position by a lock-nut key 27. Secured to the outer end of the valve-stem 3 is a handle 28, having an indicator-hand 29 ailixed to the same. The spring 24 .serves to keep the valve firmly in position in its seat and at the same time allows for the expansion and contraction of the surrounding metal.

On the outer face of the box 25 are grad uated spaces indicating when the valve is in certain positions. The position of the valve shown in the sectional view of' Fig. 3 would be indicated by the lirst sign, Opein meaning that the oil was being forced through the curved passage 5 in the valve into the concave-shaped passage 9, up through the jet 11 and sight-glass 14 into the condensing-chamber 12, down through the convex-shaped passage 10, and through the straightway passage 4 in the valve into the passage 16. In case anything should go wrong with the sight-'feed line or the sight-glass become broken the supply oi' oil to the engine need not be stopped or interfered with; but by simply turning' the valve to where the indicator-hand will point to LL Ei'nergency the oil will min'lediately How through the curved passage 5 in the valve (shown by dotted lines) direct into the passage-way 16, where it mixes with the steam, and from there is carried to the engine. Midway between the Open and Emergency points is the indication "Closed, and when the valve is turned to this point the supply of oil is entirely shut ofi", the position of the ports in the valve being shown bya second series of dotted lines. (Seen in Fig. 3.) rIhe graduations formed between the Open and Emergency points will permit of the valve 3 being regulated to feed oil through the same in any desired amount, according to the needs of the engine. l/Vhen it is desired to entirely cut off the steam condensing' in the passage 2O from the reservoir, the valve 21 is closed. This action would immediately stop the flow of oil through the head portion by shutting ottA the pressure oi' water in the tube 22.

To remove the water from the sight-glass 14 and condensing-head 12, we provideadrainvalve 30.

Seated between a hollow head portion 31, secured to and communicating with the oilreservoir, and a foot portion 32, also communicating with the reservoir, is an indicatorglass 33, leakage being prevented by packingrings and nuts 34 34.

A vent-valve 35, located in the neck of the head portion near the iilling-plug, is intended to be opened when the reservoir is being filled Afor escapement of air or gas contained therein.

1n place of the ordinary hand-valve seated in the curved passage-way 20, forming part of the condensing-line, we have shown in Eig.

8, Sheet 3, an automatic steam-actuated valve, which controls the condensation oi' steam through the tube 22, and hence regulates the supply of oil through the regulating-valve 3 and communicating passage-ways in the head portion. This automatic valve consists ofthe following combination of parts, and its use in connection with our head and reservoir portions will perfect a lubricator entirely independent of adjustment by means of the ordinary hand-valve. Connected to the eXtension 36, in which the ordinary hand-valve operates, is a steam-cylinder 37, having a sliding piston-head 38 operatively adjusted therein. Integral with this head portion is the valvestem 39, which passes through the inner end oi' the steam-cylinder 37 and enters into the curved passage-way 20, iinding its seat therein. Entering the steam-cylinder from the outer end is a stem 40, threadably seated in a plug portion 41, its inner end engaging the piston-head 38 and on the outer end being formed an operating-wheel 42. Seated around the inner portion of said stem 4() is a spring 43, the ends thereof engaging the piston-head and plug portions. Communicating' with the innerv end of the steam-cylinder is a steamsupply pipe 44, leading to and connected below the throttle-valve in the steam-line. When the throttle-valve is opened, steam is immediately introduced into the chamber 45 in the cylinder of our automatic valve and forces the piston-head forward, thus compressing the spring 43 and drawing the end oi' the valvestem 39 away from its seat in the condensing passage-way 2O and immediately starts our lubricator into action. r1`he instant steam is cut oit at the throttle of the engine the supply of steam to our automatic valve ceases, and the pressure on the piston-head being released the spring 43 will expand to its normal position and force the valve-stern 39 back into its seat,thus shutting oii condensation. 1V hen it is desired to close the valve vvhile the throttle is open, it maybe doneindependent ot' the steam-pressure back of the piston-head 38 by simply turning the hand-operated stem 40, thus forcing the valve-stem 39 into its seat in the condensing-line 20.

In the operation of our improved lubricating device oil is iirst introduced through the inlet-orifice 8 to the reservoir. The passage- IOO IIO

way 16 and nipple 18 being connected to the steam and from there caught up and carried to any part of the engine to be lubricated.

rEhe tube 17 being adjustable in the passageway 16 can be arranged so that the bell-shaped portion will always be in the center of the steam-line. Without this tube 17 the tendency ot' the oil would be to run down the inside of the steam-line, clinging to the metal; but by utilizing this tube a material saving in the amount of oil used is etfected in that steam catches up and evaporates the drops of oil as they form on the bell-shaped portion 17. Thus every particle of oil is carried to the parts of the engine to be lubricated. The steam surrounding' the pipe 19 will keep the condensation of steam therein in aheated state, and as this water passes into the passage-way 2O to the tube 22 and from there into the oil-reservoir it serves to keep the oil in a workable or liquid state, thus preventing freezing or thickening of the same.

By this system of preheating the oil contained in the reservoir ot' our lubricator we .are able to use the heaviest and thickest of oils or greases as lubricants, as they become thin and easily introduced through the valve and into the steam-line under the method employed in our device.
